key expiration

[Adam Young]

	When I first began using gnupg, I created 2 keys that both had an
expiration date 1 year from the creation date.  I was thinking this
would be a good idea, but now in hind-sight ...it's only causing me
problems.  So what I wanted to clarify, and hopefully get things
straight is:

	How exactly do I go about either a) extending expiration or, b)
revoking, and re-creating new keys

	I thought for option b, that you would:

		gpg --gen-revoke <key>
		gpg --send-keys <revoke_key>

	then go about re-creating new keys, is this the way...or am I far off
base with what is supposed to happen?
